IMPRQVEMENT IN PADDLE-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

My invention consists iu an improved mode of eonstruoting paddle-wheels,by which the whole of their working power is made available.

To make the invention better understoodl will proceed to describe it byreference to the accompanying Figure l is a section on the line A B a bof Figure 2, which vis a side elevation of apaddle-wheel constructedaccording to my improvements.

The paddle,'A A, properly so called, consists of a sheet or plate ofmetal or wood, jointed at c e to a shaft, M, the ends of which are iixedin a suitable manner to the frame-work of the wheel It.

Each paddle is provided, at`tl1e inner side of the wheel, with anextension piece, C, having at its extremity a buffer, D, and, at theouter side, each paddle is formed with a joint, b, united by aconnectingrod, E, to another joint, h., placed on the extension piece Cof the next paddle. v

All the paddles are thus united one to another, and

thelength of the rods is so regulated that one paddle is forced toincline, inl turning, on the shaft M.

This paddle acts on the two connecting-rods E, to which it is jointed atb and h in such' a manner as to draw into a radial position the paddlewhich precedes it and that which follows it. l

To insure greater rmnessto the paddle when it is drawnby the action ofthe lwater into this radial position, the buffer D, made of washers ofIndia rubber or other elastic material, strikes against an abutment, G,iixed to the framework of the wheel by means of two crank-pins, and bythis means the paddle becomes fixed.

The action of a wheel thus constructed and set in motion in the water isas follows: l

The paddle, entering the water in its radial position, will inclineunder the resistance ofthe water, andv will take an oblique direction,the two paddles next it being brought back to their radial position. Incontinuing its movement the paddle meets with less resistance, andrecovers its radial position from the action of the movement of thepreceding paddle, which becomes inclined as it passesl through thewater, and the same action takes place for all the paddles.

rlhis arrangement, which causes the paddles toyie-ld to the resistanceof the water, econoinizes the motive power, enabling it to give greaterspeed with the `'saine power and the same number of tn'rns,or ofeinploying less. power when it itis not required to increase vthe speedVof theressel. rlhe shockl is also less, and the quantity of water thrownup is diminished, thus giving amore useful ei'ect to the motive power.

I do not confine myself to the number of paddles or to their angle ofinclination, as their number and angle of inclination may be varied,according to the lapplication or speed of the paddle-wheels.

Having now described m y said invention,

The oscillating paddle A, furnished with an extension piece, C, and an'elastic bufi'er, D, attached thereto, in combination with theconnecting-rod E and the abutment G, arranged and'operating as hereindescribed.

In testimony whereof, I, the said SAMUEL BATEMAN, have hereto set myhand and affixed my seal, this thirteenth day of August, one thousandeight hundred and sixty-nine.
